I can understand the sentiment and don't fault you for it.

That said, I think you can definitely handle complex, relational patterns in DynamoDB pretty easily. It will take some work to learn new modeling patterns, but it's absolutely doable.

At what cost, though? RDBMS do provide a better querying interface with fewer pitfalls that invariably one encounters trying to fit a square peg in a round hole.

That said, I've seen people use DynamoDB as a timeseries database (modelling multi-dimensonal data with z-indices on top of the two dimensional partition-key and range-key pair), so it is definitely possible to be clever and practical at the same time.
